COMPOSITION FOR DEPOSITING FLUOROPOLYMER COATING ON POLYIMIDE FILM AND POLYIMIDE FILM COATING DEVICE |
摘要 |
FIELD: chemistry.SUBSTANCE: composition for spraying a fluoropolymer on a polyimide film is an aqueous dispersion of a fluoropolymer to which a 50% water-alcohol solution is added in ratio of 1:1. The device for depositing a fluoroplastic coating on the surface of a polyimide film has a supporting drum with a heated outer surface which is equipped with a drive which determines the rotational speed of the drum, which provides given tension in the polyimide film. The unit for spraying the fluoropolymer dispersion onto the surface of the polyimide film has a sprayer which moves across the polyimide film.EFFECT: improved adhesion and dielectric properties of polyimide films with a fluoroplastic coating.7 cl, 1 dwg |
